Waterproofing material for waterfall and bond beam/shell

[jalapenopopper]

I am building a natural rock waterfall and need to waterproof the top of the bond beam where some rocks will be installed, and parts of the waterfall pad and cinder locks that will be the base for some rocks and a water well. The structure is built for the weight.

What is a good brand and product to waterproof the shell areas the rocks will be installed on that the plaster crew will not be able to access?

There are many rubberized coatings, acrylic additives to mortar and pool paint general recommendations, but I would like to get a specific brand and product someone can recommend. I have NPT and PEP accounts and can pick up there if available.
Thanks
